About
Oscar Chapa is an instrumental astronomer whose work centers on the design and development of high-resolution, robotic optical imaging systems. His primary research focus is the COATLI project—an innovative all-sky robotic telescope that delivers diffraction-limited images with an exceptional 0.3 arcsecond full-width at half-maximum (FWHM) across a wide optical range (550–920 nm). Chapa’s major contributions lie in the systems and optical design of this 50-cm telescope, which integrates a fast-guiding steering mirror and a dual-channel imager, including a blue-sensitive EMCCD for enhanced performance. His two most-cited papers, both from 2016, detail the engineering and optical architecture that enable COATLI to achieve such high image quality over a large fraction of the sky—a significant leap for robotic observatories. With 4 and 2 citations respectively, these works have informed the development of next-generation, autonomous astronomical instruments. Chapa’s achievements demonstrate a rare combination of optical engineering and practical system integration, making him a key figure in advancing robotic telescopes for time-domain astronomy and high-resolution all-sky surveys.
